WALTER Gr. RODIGER, OF CHICAGO, ILLINOIS.

STOPPER.

Specification of Letters Patent.

Patented 9ct. 26, 1915.

Application filed. August 17, 1914. Serial No. 857,017.

To all whom it may concern Be it known that I, WALTER G. Bomann, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stoppers, of which the following is a description, reference being had to the accompanying drawing, forming part of this specification.

My improved stopper, which is a combined closure and dispensing device, is adapted and intended more particularly for use with bottles containing india drawing ink, and it has for its object the provision of an efficient closure for the bottle, combined with a dispensing device by means of which minute and uniform quantities of ink, such as a single drop, for instance, may be conveniently withdrawn from the bottle and delivered directly to the drawing pen or other draftsmans instrument, provision being also made for preventing the delivery orifice of the stopper from becoming clogged up with the comparatively heavy ink.

In the accompanying drawings, Figure 1 is a side elevation of a bottle equipped with my improved closure and dispensing device, drawn to a scale of approximately the size which I commercially employ.; Fig. 2 a trans verse middle vertical section of the same, on an enlarged scale; Fig. 3 a view of the body of the stopper or closure proper, similar to that shown in Fig. 2 but removed from the bottle, and with the delivery tube and spout and its closure removed from the stopper; Fig. 4 a sectional detail of the delivery tube and spout, corresponding to the view shown in Fig. 2: Fig. 5 a side elevation of the closure and cleaning pin fory the delivery spout;

Fig. 6 a middle vertical section of therubber cap-piece carried thereby in Fig. 2; and Fig. 7 a top plan view of said cap-piece.

The same letters of reference are used to indicate corresponding parts in the several views.

The bottle A, for the reception of the ink, may of course be of any suitable size and shape, but my invention has been designed particularly for use with small bottles of india ink, such as commonly used by draftsmen, and from which they are in the habit of filling their drawing pens and other in struments. The stopper or closure proper for the bottle, B, is formed of soft rubber, and is of general cylindrical form, but provided with projecting annular flanges a, b,

at its top and bottom. `The body of the stopper is sufficiently fiexible and compressible to permit the bottom flange b to be forced through the somewhat smaller opening in the neck of the bottle, and it is adapted to seat against the under surface of the circular' wall of the neck of the bottle, as shown in Fig- 2, while the top flange a seats upon the uppersurface thereof, so that a tight joint is formed between the exteriorl of the stopper and the interior of the neck of the bottle.

The body of the stopper or closure B is provided at one side of its center with a relatively large tubular opening or passage C, which extends entirely through the body of the stopper.` This passage is entirely open at its lower end, but its upper end is closed by a compressible cap D preferably formed integrally with and of the soft rubber body of the stopper' in the-molding of the latter'.

At` the opposite side ofthe center or diainetrical middle line of the stopper from the passage C there is provided a second tubular opening or passage E extending entirely through the body of the stopper, parallel with-the passage C, the lower end of the' passage E being enlarged in the present instance to form a circular recess F in the lower part of the stopper B, the topwall of said recess constituting an annular shoulder c surrounding the bottom of the passage E.

The passage E and recess F are adapted to receive and hold the tubular delivery spout G, which is formed of metal or other suffi ciently hard and durable material, and is provided at its' lower end with an annular flange or ring d adapted to seat in the recess F of the stopper' B, as shown in Fig. 2, and about 'midway of its length with a second annular flange or ring c adapted to seat upon the upper surface of the stopper B around the passage E therein. The soft rubber body of the stopper B is sufficiently elastic to permit the spout Gr, with its flanges d and c, to be forced through the passage E in the stopper. This may be done by inserting the upper end ofthe spout G in the lower end of the passage E, and forcing the flange e upward through the passage FJ, or the enlarged bottom Z of the spout may be inserted in the upper end of the passage E and be forced downward through the same until it seats in the recess F at the bottom of the passage. Inr either event, the spout will be nally seated in the body of the stopper, as shown in Fig. 2, with the flange d y the result that the spout G is not only securely held in place in the stopper, and effects a tight joint therewith, but presents a smooth under surface `iush with the under surface of the body of the stopper. n

vThe upper lend of the spout G is beveled off as shown, to form abeak f, presenting an inclined or beveled surface between the axial passage through said spout andthe edge of said beak. The side wall of the spout G, immediately beneath the beak f, is cut away', preferably in concave fashion, as shown at h, to form a rest vand engaging surface for the delivery end of the spout, to coperate with the drawing pen or other instrumenty when ink is to be delivered to the latter, as hereinafter explained.

The closure for the spout G consists of the head H of a pin I which extends lengthwise through the axial passage of the spout and has its pointed lower end projecting beneath the same. The head H of the pin I consists of a lower conical portion ,an upper cap portion or button j and an intermediate cylindrical portion la. Mounted upon this head H of the pin I is a softrubber cap or closure piece J composed of a comparatively thick or heavy upper portion or disk Z and an integral depending cylindrical portion m. The upper or body portion of this cap J is provided with aicentral opening n, extending all of the way through it, which permits the pin I and the conical portion of its head H` to. be j passed downwardly Kthrough the body of the cap J, so as to cause thefupper surface of the conical portion i of said head to seat against the under surface of the body of the cap J and the upper portion or cap j ofvsaid head to seat upon the upper surface theerof, as shown in Fig.

. 2, the elastic body of the cap J embracing the cylindrical portion k of the head H between the cap jl and conical portion z' and beings'ecurely held thereby.

When the vpin AI, with the cap J carried by `its head H, is laced in position in and upon the spout G, as shown in Fig. 2, the cylindrical wall m of the cap J will frictionally vengage and grip the outer surface of the spout G, and serve to securely hold the parts in position, with the lower end of the conical'portionz' of the head H and the pin I fitting in and closing Vthe upper end of gie axial orificev g of the spout, as shown in Y 1g. 2. l j

Assuming the bottle to have been previously filled with ink, and the parts to be `in .the positionshownin.Figsdand.2 of the drawing, then Inode of operation or useof vgaging surface z. of the spout adjacent the beak serving to facilitate and maintain such engagement; and with the parts in this position, the user presses the cap portion I) of the stopper B downward or inward sufiiciently to expel from the bottle a minute predetermined quantity of ink, such, for instance, as a single drop, the amount so delivered being determined by the size of the cap portion D and the extent of its depres sion or compression. I prefer and intend to make this cap portion of the stopper B of such size that a full and complete depression or compression of it, by the finger of the user as he grasps the bottle, will sulice to deliver from the bottle the approximate predetermined quant-ity of ink desired, so that the ink may be withdrawn and delivered from the bottle in substantially uniform units or quantities. If one unit is not sufficient for the supply desired at any given instance successive compressions of the cap D will produce successive deliveries of the same uniform quantities of ink.

rI`he provision of the pin I extending from the closure for the spout G entirely through the latter prevents the passage through the spout from becoming clogged with and by the ink during intervals between use, and also furnishes a ready and convenient cleansing instrument for the passage through the spout, by means of which any ink that may adhere to the surface of such passage may be removed.

The provision of the annular fiange l around the lower end of the spout G, and the seating of it in the annular recess F in 4the body of the stopper B, not only serves,

in connection 4with the flange e resting upon the under surface of such stopper, to securely hold the spout in place in the stopper and effect a leak-tight joint between them, but the provision of a smooth and unbroken surface upon the under side of the stopper and spout obviates any shoulders, or recesses or irregular surfaces which would tend to catch and hold the ink varound the bottom of the spout and clog the lower end of the passage through the same.

The rubber cap J carried by the head of the pin I serves both as a general or outer closure for the outer end of the spout G, protecting it from dust and dirt, and as a retaining means for holding the pin I and its head H in position in and upon the spout of a cylindrical body of soft rubber having annular retaining ianges at its upper and lower ends and provided with vertical passages through it, one of said passages serving to hold a delivery spout or tube and the other of said passages being closed at itsupper end by a compressible cap formed integral with the soft rubber body of the stopper, and by compressing which ink may be expelled from the bottle through the spout, such a construction being disclosed, for instance, inthe Bedington Patent No.1,026,830, dated May 21, 1912; but my improved stopper, or combined closure and dispensing device, illustrated in the accompanying drawings and described in the foregoing speciication, embodies distinct improvements and advantages over that disclosed in said patent, in the respects pointed out, and my invention consists in the features of construction wherein my device differs from prior ones, such as that mentioned, and constitutes a practical improvement upon them.
